H EAT-TRANSMITTER.

SPECIFICATION forming part of Letters Patent No. 323,545, dated August 4, 1885.

Application filed May 14, 1834. (X0 model.)

To aZZ whom, it may concern.-

Be it known that I, Josmn H. L. TUOK, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in H eat-Transmitters for TreatingUnwieldly Articles or Objects, such as boilers, &c.; and I do hereby declare the following to be afnll, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it appert-ains to make and use the same.

M y invention relates to a device for applying heat to large masses or surfaces of iron or other metal, Wh ere it would be inconvenient or impossible to subject the said mass or surface to the tire in the ordinary manner.

Asheretof'ore pursued among boiler-makers and other workers in heavy iron, the method of keeping the iron in a condition for bending, welding, 'or otherwise working it has been to subject the mass or surface to the fire, in the ordinary manner of such work, as often as it becomes cold. This has to be repeated many times on various kinds of work, and at each repetition great labor, trouble, and delay are entailed.

By means of my invention I am enabled to apply heat and flame at any point upon a mass or surface of metal without moving or disturbing the same and from a fire at a distant point, so that from the ordinary forge, hearth, or furnace used for heating the mass or surface when placed upon or in said forge, hearth, or furnace I obtain the heat and flame to apply to the metal at a distant point without any handling or labor of any consequence, and without the trouble of building a fire upon, in, under, or about the mass or surface to be treated. For this purpose I. construct and employ a hood or receptacle to place over the [ire to receive the heat, flame, and burning gases. This receptacle or hood is formed of any tire-proof material and of any appropri ate or desired formsquare, cylindrical, oblong, polygonal, or otherwise, as may be desiredwith a convergent top or dome, to the apex of which is secured afle-Xible, fire-proof tube or conveyor to lead the products of combustion oft to be delivered at the desired point upon the mass or surface of metal. This pipe may be formed of short iron or other metallic sections having knuckle joints to insure pliability and capacity for bending in any direction; or it may be made of asbestus or other naturally flexible fireproofmaterial. At the end where it is joined to the apex of the hood or receptacle a swiveljoint is provided, so that the pipe can readily be turned round at this pointand extended in any direction without twisting the pipe. At the delivery end the pipe is provided with a distributer to scatter and disseminate the heat and flame over and upon the mass or surface under treatment in such a manner as to produce the best re sults with the least expenditure of fuel or heating power. I also provide means for regulating the extent and numberof the es capcopenings for the flame and heat in this distributer, so that I can make the same distributer serve to deliver the same amount of heat and flame over a large surface, and gently or very forcibly through a small number of openings over or upon a contracted point.

The details oi. my invention, as practically applied for heating purposes on large unwieldly objects, will be more fully and clearly understood from the following description by figures and letters.

In the accompanying drawings,I have shown what I consider a preferable means for carrying the invention into practice. It will be remembered, however, that Ido not confine myself to any particular form of hood or reeeptaele, or material of which it is formed, nor the character of nor material for forming the pipe nor the size or style or the distributer on the deliver end thereof.

In the said drawings, Figure 1 is a general side elevation of the device, showing a portion of boiler-plate and a portion of the furnace. Fig. 2 is a central vertical section of the hood, showing the non-conducting covering for the hood. Fig. 3 is a face view of the distributer. Fig. at is a crosssection of the same on an enlarged scale.

Similar letters of reference indicate corresponding parts in all the figures where they occur.

Let Z represent apart of a stean1-boiler,hull of a metallic vessel, or other large mass or surface of metal, and Y the hearth ,t'orge. furnace, or other fireplace where the fire is made. Over this fire I place my hood or receptacle A.

As shown in the drawings, this is cylindrical in form over most of its body; but, as already explained, it may be ofany form. The top or dome A of the hood is conical or funnelshaped, as shown, to draw the heat and flames into the pipe B, which is to convey them off to the point of application.

The receptacle A, dome A,and pipe B may either or all be covered with some approved non-conducting material, such as is in general use for boiler and steam-pipe covers. This covering is shown at a a b in. Fig. 2.

The pipe B is secured upon the apex of the dome A by means of joint, as shown at B, which allows the pipe to be turnedin any desired direction without twisting the pipe.

The pipe is made of -anyfire-proof material, as metalor asbestus. \Vhen made of metal,it must be provided with flexiblejoints, such as knuckle-joints, as shown in Fig. 2. It may be coated both inside and outside with any approved material capable of withstanding the heat, so as to prevent the escape of heat; or the coating may be dispensed with on either the inside or outside, or both.

The pipe B may be of any desired length and at the delivery end is provided with a' distributer, O, which is shown in the form of an elongated rose or box punctured on its face so as to thoroughly scatter and disseminate the heat and flame.

In the distributer under the face I provide a slide, 0, which works in ways in the side of the distributer, as shown at C, Fig. 4, and springs C are provided to hold the slide securely in any position in which it is placed. By means of this slide I am enabled to expose the entire lot of apertures in the face of the distributer to the passage of heat and flame, or may slide it into the distributer and hide more or less of the apertures so as to condense and intensify the flow of heat and flame. \Vhen the slide is drawn out to the full extent, as shown in Figs. 1 and 3, the whole face of the distributer with its punctures is exposed to the passage of the heat and flame and the flow is gentle. \Vhen the slide is pushed in so as to allow onlya few apertures to be open to the passage of heat and flame, the flow will be forcible and intense and will heat up a point or small surface in a very short time.

If desired, the distributer may be of any other form, or a simple nozzle may be substituted for it.

As thus constructed and applied, my device will be found to possess qualities of a most desirable character, and will work with great economy of time, labor, and fuel in heating In using my device the first heat may be taken in the ordinary way, and then the subsequent heats made by use. of my apparatus, or the metal kept continuously hot by the use thereof.

The force of the furnace-blast will concentrate the flame in the hood, dome, and pipe and produce a most intense volume of flame and heat to pass out through the pipe which may be applied at any point within reach of the pipe.

As shown in the drawings, and as hitherto described, my invention has been mentioned only in connection with heating metal for purposes of working it; but in the applica tion of my device it-will not be limited to such use alone, as it will be found to be eminently useful in melting or refining ores or metals, and in many other situations where it is desirable to apply heat at a distance from the fire or source of heat.

Havingthusdescribed myinvention, what I desire to claim and secure by Letters Patent 1. The herein described apparatus for ap plyizg flame and heat, consisting of the col lecting receptacle adapted to receive and collect the heat and flame, and a fireproof eon- ,veying-pipe of flexible character. and a suitable nozzle or distributer, as set forth.

2. The combination of the collecting receptacle A, having the conical or convergent top or dome adapted to receive and collectthe heat and flame, and a fire-proof conveyingpipe secured to the apex thereof, said pipe being flexible, substantially as set forth.

3. The apparatus described for collecting and conveying heat, flame, and other products of combustion, consisting of the receptacle A, having the convergent 'top A, for location over the furnace or fire, the pipe B, united to the apex of the top A, by aswiveljoint, said pipe being formed of such material or in such a manner as to be flexible and fireproof, and a distributer, O, attachel to the outer end of the pipe, as set forth.

4. In a device for transmitting and applying heat, the combination, with the collector A, pipe B, and distributer C, of the slide 0, working under the punctured face of the distributer, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
